Hi,
The attached patches fix some compiler warnings:
plargs-patch Make sure the functions return a value.
cairo-patch Properly place parentheses, avoiding code having no effect.
I also noticed with gcc -Wall there are a lot of unused variables in
plplot, if wanted I could provide a patch which removes those variables.
Regards,
Mark de Wever
